Question

Bill weighs 150 lbs. He wants to gain 2 lbs per week for football season. Jamal runs track. He wants to lose weight so he can run faster. Jamal weighs 195 lbs and wants to lose 1 lb per week. How many weeks will it take before both of them are the same weight?

A.15***
B.45
C.115
D.345

I am confused But Believe "A" is the answer

Answer 1

I figured it out!

Answer 2

you want to create 2 equations and set them equal.

150+2w=195-1w

isolate variable

150+2w=195-1w
-150 +1w
3w= 45

divide both sides by 3

3w/3=45/3

the 3's on the left cancel out, and the one on the right simplifies to 15

w=15

(you are correct)
